All our underwear is designed to fit to your hips so they will stretch (at least*) 2cm each side, please see photos, as all us are different sizes and we try to fit the normal scale, at Wolf+Sun we have designed a fit that makes you feel great and stretches like your favourite underwear (you know the ones I'm talking about- the ones that you have worn in but you don't want to show off anymore) well never fear our designs give you that feel on the first go!
